Usher Syndrome Type 1, Deafness, Autosomal Dominant 11 (DFNA11) and Deafness, Autosomal Recessive 2 (DFNB2) via the MYO7A Gene
- GTR Test IDHelpEach Test is a specific, orderable test from a particular laboratory, and is assigned a unique GTR accession number. The format is GTR00000001.1, with a leading prefix 'GTR' followed by 8 digits, a period, then 1 or more digits representing the version. When a laboratory updates a registered test, a new version number is assigned.: GTR000506175.10
